We perform further analysis of gsf in this section. The t-SNE plot of features obtained from the output of the layer preceding the final fc layer of BNInception backbone is plotted in Fig. REF . We visualize the 10 action groups defined in [1]} in the plot. From the figure, one can see better separation of the features when gsf is plugged into the backbone cnn. This allows the model to correctly recognize the action present in the video and results in improved recognition performance compared to the baseline tsn.
